The WE120 is a feature packed GSM control unit with built-in IO which can be further expanded via its RS485 port. It has 2 relay outputs, 4 contact closure inputs with pulse counting, 2 analog inputs with support for NTC temperature sensors plus RS232 and RS485 for expansion or Modbus communications. The WE120 can call or send text message alerts on alarm and outputs can be set again via phone call or text message. With the optional temperature sensor the WE120 can act as a GSM thermostat. Programmed with the free software via USB.

WE120 is a quad band (850/900/1800/1900Mhz) GSM Modem with advanced features for remote control and monitoring, that allows both the standard data communication over the GSM network and the remote activation of electronic devices and systems.

  • WE120 has relay outputs and digital/analogue inputs, that can be set and read sending an SMS from a Smart-phone, a standard GSM mobile phone or a fixed telephone.
  • Can send an SMS to one or more registered users every time an input changes its status or crosses a pre-set threshold.
  • The Relay outputs can also be activated through SMS or voice call (ring).

The WE120 can be easily configured with SMS messages. Thanks to its flexibility the WE120 can be used in several industrial and home applications.


The WE120 can be configured and programmed sending commands and parameters using one of 4 available modes:

  • Through the free Mobile App available for Android and iOS
  • From PC through the dedicated software program Genesys 3, available for Windows, OS X and Linux
  • Through SMS messages, sent from mobile phone, with the commands and parameters required. The device will send back replies and/or acknowledge messages after command execution.
  • From PC, via RS232, editing commands and parameters with any standard terminal program (for example “hyperterminal”, available in every Windows operating system).


Using the WE120's RS485 port the IO count can be expanded by adding XP100 expansion units to 64 digital inputs, 64 digital outputs and 48 analogue inputs.
